jQuery-MXHR: A JavaScript repository from andersonbr

This is a rewrite of the original work Jordan Alperin (https://github.com/alpjor) and I did on MXHR at Digg. It's now all pretty and jQuery-ified and is actually a bit less likely to explode in your face if you use it.

Usage is modeled after $.ajax for simplicity's sake, and callbacks are set per content-type instead of per request state (i.e. 'text/html' instead of success, error, complete). Like so:

$.mxhr({
    url: '/foo/bar.mxhr',
    type: 'POST',
    data: {
      'this is a': 'post var'
    },
    'application/json': function(data) {
        data = $.parseJSON(data);

        console.log(data);
    }
});

Responses must conform to RFC1341 http://www.w3.org/Protocols/rfc1341/7_2_Multipart.html

This means that:

1. The Content-Type header must be set to "multipart/mixed"
2. There may be a boundary argument on the Content-Type header, e.g. "multipart/mixed; boundary=wharrgarbl"
3. If there is no boundary argument, the boundary string is assumed to be "--|||"
4. There must be a line after the boundary string that specifies the Content-Type of each part. Note that MXHR doesn't yet support leaving the header line blank to default to "text/plain"
5. Bonus spec-breaking fun time: You can specify multiple header lines per part with MXHR


Here's a sample request and response for a Mustache template/view combo.

Request:

var template;
$.mxhr({
    url: '/fictonal/bsg/endpoint.mxhr',
    type: 'GET',
    'text/html': function(data) {
        template = data;
    },
    'application/json': function(data) {
        view = $.parseJSON(data);
        
        //Yes, this is a race condition if the server sends the 'application/json' part first. I'm working on it.
        console.log(Mustache.to_html(template, view));
    }
});


Response:

--|||
Content-Type: text/html
Hello {{world}}.
--|||
Content-Type: application/json
{"world": "New Caprica"}
